Our Mission

The mission of the Laboratory Field Services (LFS) branch is to safeguard the health of the people of California by ensuring accurate and reliable clinical and public health laboratory testing, safe and reliable sources of human tissue and blood for transplantation and transfusion, and safe and effective biologics produced from human tissue and blood. LFS does this through licensure, inspection, proficiency testing, and oversight of clinical and public health laboratories, tissue banks, biologics facilities, blood banks, and oversight of education, training, examination, and licensure of laboratory personnel.
